Ripple CTO Emeritus David Schwartz Proposes Transaction Reservation System to Eliminate XRPL Front-Running

GateNews
XRP-2.85%
According to David Schwartz, Ripple CTO Emeritus, a new transaction reservation mechanism has been proposed to eliminate front-running and sandwich attacks on the XRP Ledger (XRPL). Following XRPresso's warning that sophisticated network participants can exploit pending transaction visibility to profit at the expense of ordinary traders, Schwartz suggested a TxnReserve system where users submit a special transaction to secure an execution slot in a future ledger, with a cost roughly twice the standard fee and limited to the next 16 ledger intervals. Once reserved, transactions would only be broadcast after the previous ledger's consensus concludes, ensuring execution priority is based on reservation time rather than network speed or privileged access. To prevent denial-of-service abuse, dynamic reservation fees would increase as available slots fill, making large-scale manipulation economically impractical.
